Abstract

The utility model provides a color LED lighting slab, relates to LED illumination, and aims to solve the problem of light spot generation after a groove is arranged at the lighting slab. The LED lighting slab adopts a direct-type LED light source, and includes a light guide plate and an LED lamp, wherein the LED lamp consists of LEDs of three primary colors RGB (red, green and blue) and is arranged on a base plate; a groove is arranged on an incident surface; the LED lamp is arranged in the groove; and a concave lens is arranged at the groove bottom and positioned at the front end of the LED lamp. Through adopting the technology provided by the utility model, the lamp panel seems to have softer and more uniform light ray distribution, and the light spot generation on the front surface of the light guide plate can be prevented. The color LED lighting slab can be applied in the fields of illumination and backlight.

Description

The color LED luminous plaque
Technical field
The utility model relates to a kind of LED lighting device.
Background technology
The LED illumination has replaced traditional incandescent lamp and fluorescent lamp gradually.The LED lamp is a spot light, and its light that sends is concentrated, and can produce dazzling effect.In order to solve the luminous dazzling and dazzling problem of LED, in the prior art, generally adopt light conducting plate structure, promptly adopt the combining structure of the LED and the LGP of straight-down negative or side entering type.
For straight-down negative LED lamp plate, this structure is that led light source is placed the LGP back, and it exists light utilization efficiency to tell somebody what one's real intentions are, and the thicker problem of lamp plate.In order to address this problem; Some improve technology and have adopted the structure of on LGP, establishing groove; As Chinese patent number be 200980107512.5, name is called " lighting device and forming method thereof ", date of publication is the file on February 16th, 2011, it mentions a kind of employing direct-light type LED backlight structure, wherein; Be mentioned to the scheme of on LGP, establishing the groove structure in this document, be used to increase the utilization rate of light.But this scheme still has problems, and for example owing on LGP, establish groove, causes LGP to become thinner than other place in the place of establishing groove, and after the LED lamp was lighted, positive at LGP, as to establish groove position can form hot spot.This is because LGP approaches the bad cause of place's light guide effect at this.The effect of this device is unsatisfactory.
The utility model content
The utility model technical problem to be solved is: a kind of LED luminous plaque is provided, establishes the hot spot problem that occurs behind the groove in order to solve LGP.
In order to solve above-mentioned technical problem, the utility model proposes a kind of color LED luminous plaque, adopts the straight-down negative led light source, comprises LGP and LED lamp, and
The LED lamp is made up of RGB three-primary colours LED, and it is located on the substrate;
On the incidence surface of LGP, be provided with groove, the LED lamp places in the groove;
Be provided with concavees lens at bottom land, concavees lens are positioned at LED lamp front end.
Preferably: be provided with reflective mirror at substrate surface.
Preferably: the LED lamp comprises LED naked core, support and heat sink, and naked core is located in the support, be erected at heat sink on.
Preferably: said groove is an open trough.
Preferably: said concavees lens are epoxy resin or silica gel material.
The beneficial effect of the utility model:
Compare prior art, the utility model is provided with concavees lens at bottom land.Concavees lens have the effect of astigmatism, and this structure makes in the middle of the LED the luminous light in strength before getting into LGP, dispersed by concavees lens, thereby avoided because the spottiness that the LED intermediate light causes too by force.The lamp plate of using the utility model technology looks that distribution of light is more even, soft, can avoid hot spot occurring in the LGP front.Because the utility model has adopted RGB three-primary colours LED, therefore, the full-color illuminating ray that this lamp plate produces is all very all even soft, and integral body presents better light efficiency.The utility model can be used for illumination and backlight all passable.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is an assembling assumption diagram.
Fig. 3 is the structure chart of LED lamp.
Identifier declaration among the figure: LGP 1, concavees lens 2, groove 3, reflective mirror 4, substrate 5, LED lamp 6, heat sink 60, support 61 and naked core 62.
The specific embodiment
The utility model proposes a kind of color LED luminous plaque, adopts the straight-down negative led light source, comprises LGP and LED lamp, and the LED lamp is made up of RGB three-primary colours LED, and it is located on the substrate; On the incidence surface of LGP, be provided with groove, the LED lamp places in the groove; Be provided with concavees lens at bottom land, concavees lens are positioned at LED lamp front end.
Below through embodiment the utility model technology is described, but the utility model is not limited to following technical scheme, the conversion that other relevant technologies can be known by inference, the replacement technical scheme all in the protection domain of the utility model.
To shown in Figure 3, this LED luminous plaque adopts straight-down negative led light source referring to Fig. 1, and it comprises LGP 1 and LED lamp 6, and LED lamp 6 is made up of RGB three-primary colours LED, and they are located on the substrate 5.On the incidence surface of LGP 1, be provided with groove 3, LED lamp 6 places in the groove 3.Bottom land at groove 3 is provided with concavees lens 2, and concavees lens 2 are positioned at LED lamp 6 front ends.RGB three-primary colours LED is not limited to the structure of each chip of three kinds of colors, also comprises multi-form three-primary colours such as 2RGB.Substrate 5 can be an aluminium base, also can be composite base plate, and it can comprise copper.
In a preferred embodiment, be provided with reflective mirror 4 on substrate 5 surfaces.Reflective mirror 4 can be the coat of metal, also can be the layer that is laid on the substrate.LED lamp 6 comprises LED naked core 62, support 61 and heat sink 60, and naked core 62 is located in the support 61, and support 61 is located on heat sink 60.Groove 3 is an open trough.Concavees lens 2 are epoxy resin or silica gel material.
